Red

Most of these are due to log jams & other friction for stuff Joe is not looking after. Pester tools committee for explicit rulez & schedule.

Z-height is visibly off, and at some point in its range the motor sound changes and it doesn’t move

This is almost ENTIRELY due to debris getting into the thin gap at the rear of the bed/airbox area. Typically it's the lower right corner too, there's a corner weld that stuff catches on. it needs to be lowered slightly and have the debris removed from the gap, then rehomed. I've rehomed the unit before, it would certainly be a good idea to have a few regulars at the space available for this since it happens a lot. the best way to prevent it is to make sure you clean out the bed and make sure small bits aren't blown off the back of the bed when you're done, also inspect that are before you start moving the bed.

Z needs to be dropped manually to the bottom before hitting re-home Z, because if you just hit re home z at the top & it jams going down it will cause the z location to be completely messed up and will require manually resetting the height by hand( a pain) so do not try this without consulting with Danny first.

'Insufficient flow from air', WTF?

Turn on the air.

Bounce the system by resetting the breakers on the bottom left in the back. Pester Danny for a low voltage power supply & spare like the Meanwell Rob already got.

Manual jogging

I have a project that has alignment marks on them and wondering if there is a way on the Red laser to move the laser head manually either by the arrows or coordinates so I can check my overlay?

There’s no way to position Red. You can do that with Blue. I do alignment in one of two ways:
1) by laying a sheet of paper on the bed and slicing it with 90% speed.
2) by cutting out a frame jig before hand.

The jig or paper lets me know where to put the item I’m cutting. If I need ~2mm precision, the paper works. Less than that, take the time to build the jig.

Cleaning
Clean the ways, wheels, & leadscrew & re-lube weekly. Z jitter can be caused by debris in the ways. If not that, it can be a worn lead nut.
